Detailed description
This clinical trial utilized acupuncture as an adjunctive treatment for glaucoma patients. It is estimated a randomized clinical trial that 50 subjects will be enrolled and observed for 12 weeks to evaluate the clinical efficacy of acupuncture, providing a reference for future clinical treatment guidelines. Participants will be randomly divided into two groups: Ophthalmic Acupoint Treatment Group and Non-ophthalmological Acupoint Control Group. Participants in the treatment group will undergo acupuncture targeting ophthalmology-related acupuncture points, aiming to elicit the 'De Qi' sensation. Conversely, the control group will receive minimum acupuncture stimulation targeting non-ophthalmic acupuncture points without the intention of achieving the 'De Qi' sensation. Both groups will undergo acupuncture therapy once a week for a total of six sessions and will be observed for twelve weeks. On each visit, intraocular pressure, blood pressure, and heart rate will be assessed. Questionnaires of Glaucoma Symptom Scale (GSS) and The Glaucoma Quality of Life-15 (GQL-15) will be performed. The data of central corneal thickness, optical coherence tomography angiography, optical coherence tomography, visual field, and best-corrected visual acuity will be collected and analyzed before acupuncture and in the 12th week.
Interventions
OTHERAcupuncture
The treatment will take place once a week, over six weeks. The needles will placed in the body for 20 minutes. A total of 12 Needles(6 acupoints, bilaterally) will be used in each session.Participants in the treatment group will undergo acupuncture targeting ophthalmology-related acupuncture points, aiming to elicit the 'De Qi' sensation.
OTHERAcupuncture placebo
A total of 12 Needles(6 acupoints, bilaterally) will be used in each session. Acupuncture points are different from the experimental group.The control group will receive minimum acupuncture stimulation targeting non-ophthalmic acupuncture points without the intention of achieving the 'De Qi' sensation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intraocular pressure-pre-treatment | Every weeks pre-acupuncture treatment up to six weeks. | Intraocular pressure (IOP) is the fluid pressure of the eye.TOPCON CT-80 Computerized Tonometer is used for measurement.The unit of value is mmHg. |
| Intraocular pressure-after-treatment | Every weeks 15 minutes after acupuncture treatment up to six weeks. | Intraocular pressure (IOP) is the fluid pressure of the eye.TOPCON CT-80 Computerized Tonometer is used for measurement.The unit of value is mmHg. |
| Intraocular pressure-Change | Change from baseline intraocular pressure at 12 weeks. | Intraocular pressure (IOP) is the fluid pressure of the eye. Tonometer is used for measurement.The unit of value is mmHg. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Central corneal thickness | On the first and 12th week for baseline and follow up tracing. | To measure mean values of central corneal thickness (CCT) obtained by specular microscopy. |
| Glaucoma Symptom Scale | On the first and 12th week for baseline and follow up tracing. | The Glaucoma Symptom Scale (GSS) is a simple and brief glaucoma-specific questionnaire aimed at quantifying complaints and functional impairment in patients with glaucoma. We used 1998 version of the Glaucoma Symptom Scale (GSS; Lee et al., 1998) Questionnaire.The items include 10 ocular complaints, for each eye, a 5-level score is generated, ranging from 0 (complaint present and very bothersome) to 4 (complaint absent). This score is then transformed to a 0 to 100 scale, with 0 representing presence of a very bothersome problem and 100 representing absence of a problem. |
| Glaucoma Quality of Life - 15 | On the first and 12th week for baseline and follow up tracing. | The GQL-15 questionnaire is composed of 15 items. A 5-point rating scale for the level of difficulty of each task totals a score from 0 to 75. A higher score signifies a poorer . |
| Blood pressure | we measure blood pressure every weeks before and after acupuncture treatment of totally six weeks, and first and 12th week for baseline and follow up tracing. | We measure the blood pressure of patient before and after acupuncture treatment .Both systolic and diastolic blood pressure will be measured. |
| Optical coherence tomography-RNFL symmety | Change from baseline RNFL symmety at 12 weeks. | The optic disk and the RNFL are the principal sites of apparent glaucomatous damage which precedes glaucomatous visual field alterations. RNFL symmety and Retinal nerve fiber layer (RNFL) thickness measurements obtained with Optical coherence tomography employs low-coherence interferometry.The unit of value is %. |
| Best corrected visual acuity | Change from baseline best corrected visual acuity at 12 weeks. | Best possible vision a an eye can see with corrective lenses, measured in terms of Snellen lines. |
| Visual field- mean deviation | Change from baseline visual field at 12 weeks. | The visual field refers to the total area in which objects can be seen in the side (peripheral) vision as you focus your eyes on a central point. Visual field will measured with automated perimetry.The unit of value is dB. |
| Visual field- visual field index | Change from baseline visual field at 12 weeks. | The visual field refers to the total area in which objects can be seen in the side (peripheral) vision as you focus your eyes on a central point. Visual field will measured with automated perimetry. Visual field index intuitive presentation may underestimate the visual loss. |
| Heart rate | we measure heart rate every weeks before and after acupuncture treatment of totally six weeks, and first and 12th week for baseline and follow up tracing. | We measure the heart rate of patient before and after acupuncture treatment . |
| Optical coherence tomography-C/D ratio | Change from baseline C/D ratio at 12 weeks. | The optic disk and the RNFL are the principal sites of apparent glaucomatous damage which precedes glaucomatous visual field alterations. The cup/disc (C/D) ratio as a standardised method to evaluate the optic nerve obtained with Optical coherence tomography employs low-coherence interferometry. |
| Optical coherence tomography angiography-RPC density | Change from baseline RPC density at 6 weeks. | Optical coherence tomography angiography is a relatively new, non-invasive, dye-free imaging modality that provides a qualitative and quantitative assessment of the vasculature in the retina and optic nerve head. We use OCTA to complement visual field and OCT examinations to diagnose glaucoma, detect progression and evaluate the treatment of acupuncture. Using OCT angiograms, the RPC density was evaluated quantitatively. The unit of value is %. |
